.slide carriers', for,stereoptieon lanterns, and

has for its objects, the provision of a slide carrier, that will ail'oi'd every facility for the easy and extremely rapid change of transparen cies or slides with the minimum amount of labor and care, on the pai-t of the operator, and in which a 'full`set o'l" said slides,.wi1l be. exposed in their consecutive order, and iii Vwhich each and every slide iii said set, will be brought. into exact register with thecoii- (lensing lenses in said lantern; iurtlier objects are, to so arrange and construct a slide carrier,- that h v its use-the. soiling and breaking ol" slides will be. inexcusable, on the part ol the operator, and to construct a slide carrier thatsliall be neat in appearance, durable and-be extremely chea` i in cost of manufacture; and be adapted lor use inv connection with the variously constructed lanterns now in o eration. vl attain these objects by the mec ianisin illustrated in the. accompanying drawing, in whichz-- Figure 1. is a vertical section, cut on the line X seen in Fig. Fig. 2.- .is a longitudinal section ol' the carrier and o'l'4 a lantern, cut on the line Y Y, seen in Fig. 1. Fig. S is an enlarged vertical section, in detail of the ways and carriage stop, cut on the'liiie. Z 7i, seen in Fig. 2. Fig. Yl is an enlarged view in perspective olwone ol' they slide holding l,Lleviecs.

Myinvention comprises a wheel 1, rotatable on stud 2, secured in the, upper end of ariir bracketl I, secured on carriage 4, slidable. in ways 5, secured by screws oii base mounted Aon an ordinary table 7; carriage 4 has its inward movement limited hy carriagestop', adjustahlyV secured iii ways 5, by thumb screw t), adapted to'l'orce stop S upward against ways 5; wheeld is provided with spokes l", on the outer end portions of which is mounted the annular aperture piece lt), inrfwhich is formed the apertures l1, adapted to becovered b vslid'es l2, reinov ably held in. place over said apertures by .ilanges 13 are each provided with a s ring 14 secured on the inner side thereof, iiy rivet 14, and ada ted to press one edge of a slide 12 and togetlier with its opposite ati-d` duplicate device to press said slide .against ieee 10, and to removably hold said slide in ace, between slide holding studs 12 a'nt 12b, formed on piece 1() as seen in Figs. 1 and 2.

vPiece 1() is provided with V shaped register notches l1.5,v formed in the periphery therel of, and are normally engaged by Ithe V shapeddoer 16 formed on spring 17seoured in tube holder 18, hyrivets 1'7"; spring 17 is extended tlirouglraperture 18a', in said tube holder and terniinates as a thumb piece 17 b, for manually moving said dog, if in operation', sucli'shoul'd become necessary. j'

'llie ordinary lamp house 19, of 'a Stereopticoii lantern, laterally slidable on rods 20,A longitudinally adjusta'bleon rods 21, (seen in-l1`ig. 2.,) is provided witlilout'wardly'olirved front and rear sides 18?,oftube-liolderjlB,

flanges 13, secured on aperture piece ;l

.adapted to receive the heretofore described slide carrier between them.v

In the o )eration of the slide carrier, a series ol slides 12 are, in consecutive order, each passed over one of the slide holdin studs 12, and between the springs 14 an piece 10 until stopped by studs 12", after which said slide is i'eleased'and springs 14 presses said slide against piece 10 an( between sliih` holding studs 12*l and 12"; lamp house. It) is moved on rods 2t), to the position seen, a'l'ter which carriage 4, carrying the described slide carrier, is moved in ways 5 until slide'l2 is iii register'witli condensing lenses 22, with dog l() resting in register notch 15,k

al'tei'nliicli, slide 12 is ready for ex and al'ter its proper timeol' exposure pired, the operator, (not showin) grasps the edge ol" piece l0 and overcoming spring 17, i'orces said piece and its attached parts to rotate on stud 2, until the next aperture 11, covered' li'y the next -slide 12, is brought iii register wit h,condensing lenses 22, aud so on, until the entire series ol` slides 12 are exposed, .al't er which the said series of slides or any part thereol', as desire( repeating ol choruses, in illustrated songs, and the like) may again be exposed. It will posure, ias exbe seen from the foregoing that slides 12,041.11 not be exposed out ol their consecutive order, unless they have previously beeiriiriproperly placed in the described slidecaiiicr.

It will readily be understood, that Where a lantern slides therein; a base for said slide lamp house 19, slidable on rods 20, is use d, carrier Ways,` secured on said base,acarria e, vthat the 'once adjusted carria e 4, and parts ada ted to travel in said Ways and to e carried thereby are not move I laterally, but guid) sthatsaidlamp house is moved laterally on riage, and a bracket, secure onA said cared thereby; a stop for sto pingsaid car- 35 rodsr20, as is usually donein order to bring ria e, and arranged to rotatably support said I lenses 22 in register with other and different sli e carrier. apparatus, not shown, and after such use is 2. In a slide holder of the class described,`a returned, as described, in register again with rotatable annular aperture piece, having a 40 10 slide 12. In rases where said lamp house is series of apertures therethrough, and a series not moved laterally, the described slide earof register Anotches formed in the periphery rier is caused to move from between the thereof;y flanges secured on said aperture sides 18, of' tube holder 18, by moving carpiece, adapted 'to removably hold a series' of ria'ge' 4', (guidedby Ways 5,) from carriage ordinary lantern slides'on said piece, and in 45 15 stop 8. t will be seen and underst0od register With said a ertures; springs secured vfrom the foregoing, that said operator does on the inner sides o said flanges, and adapt'- not handle the slides12, after the same have ed to pressgsaid lantern slides against Vsaid I -once been placed in the described carrier, as aperture piece and slide holdin studs,formed long as anyeertajn series of said slides are in on said' aperturepiece for'ho'l ingsaidslides 50V 2o continueduse., and that therefore said slides in register with said apertures, and registerare-notin any Way subject to ,be either soiled ing means, for engaging said notches in said or broken, and that the change from one aperture piece, for normally registering the slide 12 to `another-slide can be done Withthe. a ertures throu h said aperture Apiece With utmost easerapidityfand precision. t e eondensing.. enses of an ordinary stere- 55 25 Having fully described my invention, what opticon lantern. y
